Using f(x) = log x, what is the x-intercept of g(x) = log (x + 4)? Explain your reasoning. help please! Even these simplest questions get me stuck.
Answer:
The x-intercept is at (-3, 0).
Step-by-step explanation:
log 1 = 0, so the x intercept of y = log x is at (1, 0).
The + 4 in the parentheses moves the whole graph 4 units to the left.
Therefore the x-intercept of log(x + 4) is where x = 1-4 = -3.

The car can travel 360 km with 24 liters of gasoline.
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
A car consumes 6.8 liters of gasoline for every 102 kilometers traveled.
6.8 liters of gasoline = 102 km
1 liters of gasoline = 102 km/ 6.8
= 15
24 liters of gasoline = 24 x 15 = 360
Hence, The car can travel 360 km with 24 liters of gasoline.

Which equation can be simplified to find the inverse of y = 5x² + 10?
Answer:
See below
Step-by-step explanation:
Here is how to start....you didn't include the equations in question, so I do not know what the answer may be
solve for x
y-10 = 5 x^2 divide thru by 5
(y-10)/5 = x^2 'sqrt' both sides
± sqrt( (y-10) / 5 = x change x's and y's
± sqrt ((x-10)/5) = y

Sally has 10 pounds she wants to buy 28 cans of soda which cost 28p each does she have enough money
Answer:
Yes, Sally has enough money to buy 28 cans of soda.
Step-by-step explanation:

The average vehicle releases 1.39 grams of nox per mile driven. if a vehicle is driven 22,000 miles per year for 15 years, how much nox does that vehicle release
In 15 years, the average car releases 458.7 kilograms of nox.
How much nox does that vehicle release?
We know that the average vehicle releases 1.39 grams per mile driven.
And, in average, that car drives 22,000 miles per year.
So in a year, a car releases:
M = (22,000)*1.39 g = 30,580 g = 30.58 kg
In one year, the average car releases around 30.58 kilograms of nox.
Then in 15 years, the car releases 15 times that amount, then we have the product:
T = 15*30.58 kg = 458.7 kg
In 15 years, the average car releases 458.7 kilograms of nox.

After 4 years, approximately how much will marcia have saved in interest by consolidating the two balances? a. $1,890.24 b. $133.92 c. $543.84 d. $1,346.40
The amount that Marcia will have saved in interest by consolidating the two balances is: b.$133.92.
Amount saved in interestFirst step
Calculating for credit card A monthly payment (12% APR) using financial calculator
=pmt(rate,nper,-pv,fv)
Where:
Rate=12%/12=1%
Nper =12 months×4 years=48
PV = $1,389.47
FV=0
Hence:
=pmt(1%,48,-1389.47,0)
=$ 36.59
Second step
Monthly payments 16% APR=$39.38×48
Monthly payments 16% APR =$1890.24
Monthly payments 12% APR=$36.59×48
Monthly payment 12% APR=$1756.32
Third step
Amount saved in interest=$1890.24 -$1756.32
Amount saved in interest=$133.92
Therefore the correct option is B.

The volume of a brick 3 inches wide, 8 inches long, and 4 inches tall is:
15 square inches
36 square inches
44 square inches
96 square inches
Answer:
96 cubic inches
Step-by-step explanation:
Volume=length*width*height
Your unknown is volume, which we can simplify as V.
Plugging in for the values of length, width, and height, we get [tex]v=8*3*4[/tex]
From there, we can simplify.
[tex]V=8*3*4\\V=24*4\\V=96[/tex]
To get the units, we know that the length, the width, and the height all are measured in inches.
[tex]V=inches*inches*inches\\V=inches^2*inches\\V=inches^3[/tex]
[tex]inches^3[/tex] can also be written as cubic inches, or inches cubed.
This gives you the answer of 96 cubic inches.
